Right Triangle Trigonometry Trigonometry is a branch of mathematics involving the study of triangles‚ and has applications in fields such as engineering‚ surveying‚ navigation‚ optics‚ and electronics. Also the ability to use and manipulate trigonometric functions is necessary in other branches of mathematics‚ including calculus‚ vectors and complex numbers. Right-angled Triangles In a right-angled triangle the three sides are given special names. The side opposite the right angle is called the

IB Math SL Portfolio Body Mass Index (Type II) AmyXu April 11th/2012 In this portfolio‚ there will be investigations on the topic of the relationship between females of different ages and their body mass index (BMI-a measure of one’s body fat). Body mess index is calculated by taking one’s weight (kg) and dividing by the square of one’s height. ___________________________________________________________________________ While growing up‚ the

sums of the Fourier series for a square wave In mathematics‚ a Fourier series (English pronunciation: /ˈfɔərieɪ/) decomposes periodic functions or periodic signals into the sum of a (possibly infinite) set of simple oscillating functions‚ namely sines and cosines (or complex exponentials). The study of Fourier series is a branch of Fourier analysis. Contents [hide] Definition[edit] In this section‚ s(x) denotes a function of the real variable x‚ and s is integrable on an interval [x0‚ x0 + P]

triangle. If the length of one of the sides is known‚ the other two are determined. These ratios are given by the following trigonometric functions of the known angle A‚ where a‚ b and c refer to the lengths of the sides in the accompanying figure: Sine function (sin)‚ defined as the ratio of the side opposite the angle to the hypotenuse. \sin A=\frac{\textrm{opposite}}{\textrm{hypotenuse}}=\frac{a}{\‚c\‚}\‚.

the ES2 synthesizer open was change the default preset to plain sine. Next‚ shorten the attack significantly. Then‚ I shortened to the decay to a little less than half‚ took away all of the sustain‚ then shortened the release to about 1/6. Then‚ I changed the settings so that the pitch will be modulated by envelope 2. After‚ I turned on the filter and set the drive to about 0.10 to give some realistic harmonics. Finally‚ I set the sine level up a bit to give a bit more of a bass sound and voila! The

What is the phase shift for the following? a. A sine wave with the maximum amplitude at time zero b. A sine wave with maximum amplitude after 1/4 cycle c. A sine wave with zero amplitude after 3/4 cycle and increasing Solution: a. There is no phase shift at time zero b. (¼) 360 = 90 90 x 2π / 360 = 1.57 rad c.
